Occasional Issue with Writer and Calc (Version: 6.2.2.2)

Hi

This is just a note because I can't recreate the problem at will or identify the circumstances when it happens.
There are times when editing a document or worksheet, i loose access to the document or worksheet workspace but i can still access the menu bars etc. I have to close the document and reopen it to be able to continue typing.

regards

Ian
