Description:
When I'm choosing Validity > Cell range function and trying to select a cell range, I can't select it. I can't also switch to other sheet. When I close Validity dialogue, I can't any more switch other sheets and I can close the file only by killing application, while I can close the writer windows.

Steps to Reproduce:
1. Open LibreOffice Calc with a new, empty spreadsheet.
2. Create a second sheet (Sheet2) and enter some data into cells A1:A5. This data will be the source for the data validation list.
3. Go back to the first sheet (Sheet1).
4. Select a cell where you want to apply data validation (e.g., cell B2).
5. Go to Data > Validity....
6. Select Cell range and double click on Source so that small Validity window appears.
7. Move mouse to spreadsheet cells area and try to press on Seet2 or select any cell range in Sheet1. 

Actual Results:
It is not possible to select cell range in Sheet1 and not possible to switch to Sheet2, respectively, it is not possible to select any cell range. After closing Validity dialogue I can't switch to Sheet2 and I can't close file.

Expected Results:
I should be able to select any range in Sheet1 and switch to Sheet2 to select any range there.
