Description: It may be either a "self-imposed limitation" based solely upon the amount of memory available to the application or a failure to paste a single item into exceptionally large blocks of data. If it is indeed self-preservation then perhaps a warning should be given. However, I have managed to force the copy process to continue into the entire sheet causing memory error crashing and total dedication of the processor to interrupt processing. Steps to Reproduce: Create a new empty CALC Select the entire sheet with the cell/space between column and row headers - the "master cell" Observe the entire sheet is defined in the address box Observe the text format is identified for the entire matrix Amend the font or the weight to anything you desire Focus on a random cell and observe the new characteristics are replicated for every cell. Clearly, the "master cell" focuses everything Scenario 1 type a single character into A1 and copy the contents Select the entire sheet with the "master cell" Attempt to paste the memory contents by any means available Nothing happens Scenario 2 Focus and copy A1 then ctrl+shft+right Paste and paste special both fill Row 1 with the character Scenario 3 Having filled row 1 it is still in focus, copy row 1 select the "master cell" - everything is in focus and will accept any command to copy Whilst it accepts the command it had catastrophic results on my PC Scenario 4 Clear the sheet and type a single character into A1 Type a single character into AMJ1048576 - the last cell in the sheet focus either A1 (or AMJ1048576 as you're already there) and copy the cell contents Select the entire sheet with the "master cell" Attempt to paste the memory contents to the selected array by any means available Nothing happens Scenario 5 Place a character into each of the sheet corner cells Copy any one of the four populated cells then select the entire sheet with the "master cell" any attempt to paste will fail Scenario 6 With data in each of the sheet corner cells Copy one of the cells then select the entire sheet with the "master cell" By incrementally editing the matrix address in the address box towards a substantial reduction of the row number, there will eventually be a reaction to a "paste" by confirmation of the desire to overwrite existing data. I never finalised this copy attempt as I try to avoid too many disaster recoveries and impose a personal limit of one per day. Actual Results: Failure to complete all copy processes and system crash Failure to provide system limitation warning Expected Results: faultless copy or warning that the system limits may be breached by this operation Reproducible: Always User Profile Reset: Yes OpenGL enabled: Yes Additional Info: Build ID: 9a9c6381e3f7a62afc1329bd359cc48accb6435b CPU threads: 4; OS: Windows 10.0 Build 19042; UI render: Skia/Raster; VCL: win Locale: sv-SE (en_GB); UI: en-GB Calc: threaded i5 3.4Ghz 8GB RAM
So what. You proudly managed to navigate the application into a DOOM state where your machines memory is exhausted. Now what.
(In reply to Eike Rathke from comment #1) > So what. You proudly managed to navigate the application into a DOOM state > where your machines memory is exhausted. Now what. This resulted from some simple experiments to ascertain why hiding columns is instantaneous but hiding rows challenges the capacity of a CRAYII. I think not providing a warning is about as amateurish asssss, let's see now.... your response - which says more about you than anything else.
Further experiments have identified that a Microsoft product - "Mouse without Borders" - which has the capacity to permit clipboard pasting across computers, will "reserve" the same amount of memory that is being allocated by LO to the clipboard during LO's "copy-paste" process. This allocation occurs despite the fact that the "allow pasting across computers" parameter is disabled AND due to a key change, the product has not even recently been "paired" with the other three PCs. The memory hog is indeed MwB which simply replicated the ever-increasing memory requirements of LO with the re-doubling of the clipboard to increase the speed of "copy-paste". Yes, MwB has subsequently been reassigned to the RatBin Presumably, that means SOLVED NOTABUG
