Hello

After install of version 7.4.1, problem with Calc :
* opens xls ans xlsx files in read-only mode, stating unability to lock the file for modification or wait for an alert as Calc is unable to lock the file
* also "save as" impossible, and also export to pdf

Verified security permissions on directories ==> OK

Uninstalled 7.4.1 and went back to 7.3.5.2 : problem solved

Hope it helps.
