Windows 7: Multitasking Issues

I installed 2 windows updates last night, one optional one important. Now it seems when I have mIRC 6.35 with NoNameScript 4.22 open and try to click firefox in my taskbar, Firefox will no longer pop up. I have to click the NNScript icon in the taskbar to minimize to be able to switch to Firefox. Is any one else having similar problems since the last updates? KB2607576 and KB2603229 are the updates I am referring to.

A Jump List that contains more than 999 items is not displayed in Windows 7 or in Windows Server 2008 R2

That one has to do with a jumplist issue. So my inclination would be to think it's more likely the cause.

Thanks, so should I uninstall and then tell windows update to ignore the update?

Any time you make a change make sure you can get back to the start state. I would try backing it off and see what happens.

In addition to restore points I find it good to back up Registry with ERUNT

and make an image of my system partition at least, to an external drive. You can find free imaging programs here:

Free Hard Disk Backup and Restore, Hard Disk Image and Cloning Utilities (thefreecountry.com)

Well I uninstalled the update through programs and features. No luck there. I have a system restore that I can try, but I generally dont like using them, only as a last resort.

EDIT: Tried a system restore, but no luck. Thank for the information but none of that actually fixes the problem at hand.

Another reason to have multiple system images. If you keep the system partition lean you can restore from external USB 2.0 in about an hour. Much faster if you have USB 3.0 or ESATA. If you only rely on restore points there's not much room to maneuver.

Again preaching about back ups does nothing to resolve the issue. It is good information, but it is a precaution, not a solution in this case.

To further up date, I tried to uninstall both the updates. No joy. I remembered I had installed a few apps in the past few days. I only needed them for a single usage as I had used a sound recorder app on my phone that decided to record in raw PCM format rather then WAV. I tried a few different apps to convert to WAV so it could be posted for review. I removed those thinking it was possible that one of them some how managed to cause system conflicts. There must be some way to resolve this problem. I may do a format and secure erase on my SSDs(RAID setup, so no TRIM) and go for a clean install but this is my preferred last resort.

Making changes to your system with no backup invites the predicament where there is no solution other than to wipe and start over. That's the point. I can't undo what you've done from here.

Have a go at uninstalling NoNameScript 4.22 ? Maybe a reinstall of FF would help too.

Also I would keep watching those 2 update numbers on Microsoft site. If there's a side effect on many systems they might issue a fix for the fix. It's happened before.
