Could be a video related problem.. maybe a driver problem... do you have all the latest drivers installed? All the Windows Vista drivers are supposed to work on Win 7... and there are a few Windows 7 drivers out there already and many more to come... Is that the only problem you are having??
It could also be that your copy of the Beta has become corrupt... there are some ISO's with slipstreamed malware in them floating around out there.. I'd wait for the public Beta to be released and see if you have better luck with that.. if your unable to fix the problem first..
i am having the same exact problem where i can't close, resize, maximize or minimize any windows. but it only started happening today. just last nite i was using windows 7 and everything was fine. i dont think i made any changed since then.
I'm having the exact same problem. Resizing applications from Task Manager works fine. Sometimes it starts working after 10 minutes, sometimes an hour, sometimes not at all. Installed new Nvidia drivers and on reboot it didn't occour, but after another reboot the problem returned. Also, sometimes buttons in dialogue boxes don't have text. Also, you can't get the old style context menu when you Shift-Right Click an app in the task bar.
Do the other people suffering this problem have Nvidia cards?
Also worth noting is that if you turn off aero and change to classic grey windows the X is actually greyed out.
I'm having the same problem but it only happens when my daughter logs in on her account can not resize or close the window have to close from taskbar. When I log in every thing is fine. It doesn't happen when I'm logged inn.
The weird thing is it. doesn't happen all the time. I have a Nvida card and the latest drivers. Maybe a rollback to earlier driver might help?
I've tried creating another test account but it does it in that too.
My gut feeling is it's going to be an Nvidia thing. Regarding the rolling back the drivers I'd had the problem with the 'built in' nvidia drivers.
I think the strangest thing is that it starts working after a length of time. If I'm honest I haven't troubleshooted this to a great extent because I just maximise firefox and work in tabs. One thing I notice when I breifly looked into it was services were finishing loading a long time (minutes) after the systems had seemingly finished booting up. This might be linked to the problem. Maybe the way services are loaded has changed in Windows 7?
I'll do some more thorough troubleshooting at the weekend with an ATI card and investigating the event logs.
Hey, there is a problem with the account creation file in Windows 7. The first account made (Administrator) Or the profile you created works completely fine right? When you try create another account it works, but you have the following errors. (Cannot resize window, Cannot Close Window, Cannot Enlarge window) -- The problem is in the AppData in the Users Folder. (This folder is hidden) -- Quick solution, copy the first user you created (their AppData) Folder into the users you want to able to fix those problems. there will be a few things you wont be able to copy, but just skip those. Once you've done copying it, you are all ready to go.
There are other problems with Windows 7, but i'm sure it'll be easy enough to fix. Took me 2 minutes to figure out how to fix the resizing. Anyway, enjoy.
