Unstoppable Cell Selection in Microsoft Excel

In Excel, moving the mouse anywhere on the screen will result in selecting all cells the mouse passes over. Excel does not respond to the right or left-click and can only be closed forcibly. In other words, the mouse cursor behaves as if the left-click is being pressed while in Excel causing it to do nothing but select cells indefinitely.

I believe this issue to primarily be a conflict with the Novell GroupWise Office integration (ODMA) for Microsoft Office. Secondarily, it may be an issue with the mouse driver.

Resolution:

1. In GroupWise, turn off or uninstall integrations (who likes them anyway?)
2. Search the computer and remove any instances of GWxl97.xla or GWXLUS.XLA.
3. In Excel, reset the Worksheet Menu Bar by going to View > Toolbars > Customize > Toolbars… then select “Worksheet Menu Bar” and hit Reset… This screen also shows a “Standard” toolbar which sometimes must also be reset.
4. Reboot.
5. If the issue persists, remove the mouse driver, reboot, and allow Windows to install a generic driver.
6. If the issue still persists, remove the mouse driver, install the driver specific to the mouse and reboot.
7. If the issue persists, then it’s not an issue with GroupWise integrations or your mouse driver. Good luck!
