I have one user who has severe mouse problems inside a spreadsheet that has been executed from AccuTerm.  If the same spreadsheet is opened from Excel itself or from the file explorer, everything works normally.  The problem is a severe lag in any mouse commands.  If the user clicks on a cell, it is 2 to 5 seconds before the cell that was clicked on becomes selected.  If the user tries to drag a selection in order to select multiple cells, there is also a severe lag.

The user is on the latest version of Accuterm I have which is 8.1.2.1137.  The mouse pattern file is identical to what I and other people are using.

Has anyone encountered this before?
