Desktop Gadget Problem

I have searched the threads on this one but nothing seems to fit my problem.

Three times recently when starting my computer (Win7 Pro 64 Bit) a Desktop Gadget has been missing from the desktop (Not always the same gadget). If I go to Control Panel, Desktop Gadgets will not open and "Restore Desktop Gadgets installed by Windows" in Appearance and Personalization will not open either.

If I restart the computer all is back to normal and working as it should.

Any thoughts please?

Use Anti malware bytes to scan for viruses. Because that sounds suspicous...

how did you get that sig?

Thank you A Guy. I have run System File Checker and all is well. But I don't actually have the problem at present, perhaps I should repeat when the next gadget goes missing.

Eddowii, I have Norton Internet Security, will Malware Bytes cause a conflict?

What do you mean by "how did you get that sig"?

I think the problem is pretty common. I have it too, and I just manually put my gadget back on my Desktop when I realize it's not there. My gadget is a calendar/clock that came from the selection of gadgets for the Vista Sidebar. It may be just an inherent problem that the Sidebar had --- and perhaps that's one of the reasons why MS changed (essentially eliminated) the Sidebar in Windows 7.

I've noticed that a number of apps work well when you first install them, and then, somehow down the line, they can get corrupted and not work consistently well. This has happened, not only with my calendar/clock Sidebar Gadget, but also with my DigitalPersona fingerprint reader software and my Fences.

Thank you Imperfect1. The problem is that when a gadget goes missing at startup Desktop Gadgets in Control Panel will not open.

I will try Malware Bytes but I think NIS should have picked up any problems.

Thanks all.

The Malware Bytes scan is all clear.
