OfficeTab now works OK for me!
(and presumably it could for you too).
Though this was a really useful Add-in to MS Office, on my laptop it had only seemed to work in Excel and PowerPoint, but not for Word (where I could have put it to good use). This was despite my not insignificant efforts to try to discover and "fix" the problem.
When I started up Word today, I discovered to my pleasant surprise that OfficeTabs now works a treat in Word as well.
The only thing that I had changed and that I think
(no proof!) could have brought this about was that I had happened to use CCleaner (for the first time ever) - albeit with some trepidation - to clean some redundant garbage out of my system. So, I suspect that something was blocking the Add-In from working and CCleaner removed the blockage.
So, all you people (above) who tried OfficeTab and it didn't work or behave nicely in some way - well, it might not hurt to install OfficeTab, close all MS Office applications. Then, if OfficeTab does not work as it should, run CCleaner, reboot the PC, and restart the MS Office applications.
If you try this, then let us know how you get on please.
