Windows 7: Lost smooth transition effect on thumbnails from TaskBar

Hello:

I upgraded my system (Dual Core 3.4GHZ Intel based server with 4GB RAM) from Vista SP2 to Seven SP1 (32 bits). At first login, when I hovered the mouse pointer over the taskbar icons to get the thumbnail preview, I got this nice smooth transition effect between icons.

But after a few days of use I lost the smooth transition effect; thumbnails now change in a fast, direct way.

I did a repair install to ensure system integrity; smooth effect was recovered after repair install.

But now, 2 days after repair install, smooth transition is gone again.

Already did a sfc /scannow and no integrity problems revealed.



Also tried a Microsoft Fix it for areo Glass, and other troubleshooting procedures; but no problem was detected.

Any ideas on how to recover the smooth effect, and what the problem might be?

Thanks.

Thanks for your welcome, A Guy!

Provided registry tweaks modify delay time (time it takes for thumbnail to appear) but none restores the smooth transition effect.

Not a big deal to have lost this effect, but as a programmer always wonder why?

Thanks anyway. Let see if we get more ideas on the road.

I'd suspect something software or hardware is interfering. You might try performing a clean start to see if it works ok then.

After repair install made on April, 12th I backed up the registry. I did a registry restore to April 12 (used ERUNT) which recovered the smooth transition effect.

The effect loss is caused by software installed before this point. Don´t know yet what application causes the issue.

Issue solved for me with the registry backup.

A Guy is right it is a software problem coming from another application. Thanks to A Guy!

Glad you got it sorted, and are an Erunt user I'm assuming you won't need this, but just in case:
