When trying to drag any Office program open window using the mouse, the drag is very slow, severely lagging behind the mouse motion. This only happens with Office programs, all other windows work normally. This issue started about a month ago with a windows/office update.

I have tried the following:
Reinstall the latest mouse drivers,
Three different mice, one USB, One USB wireless, one Bluetooth
Update Windows and Office

Nothing made any difference. When this happens, there is plenty of available memory, and CPU capacity. This seems to be a problem only related to Office programs.

Previous posts on this do not seem to address the same issue with only the Office programs.

Any ideas how to correct this?
