User-Agent:       Mozilla/5.0 (Windows; Windows NT 6.1; WOW64; rv:2.0b3) Gecko/20100805 Firefox/4.0b3
Build Identifier: Mozilla/5.0 (Windows; Windows NT 6.1; WOW64; rv:2.0b3) Gecko/20100805 Firefox/4.0b3

happens most of the time when more than one tab is opened. 

Reproducible: Sometimes

Steps to Reproduce:
1.open several tabs
2.minimize
3.try to restore

Actual Results:  
ff becomes unresponsive. Only way out is to terminate Firefox from task manager. Oh yes, hovering over the tabs thumbnails in Win7 task bar still make corresponding windows appear restored  as long as the mouse pointer is on the thumbnails, but there's no way to have them remain on the screen permanently. That's when FF must be terminated manually. When relaunched, just a blank page appears instead of my homepage, this is fixed by clicking on the home button.


this is a new issue, never happened with 4.0b2

I'm on the latest 4.0b7pre and it still happens >>> FF freezes when minimized with more than one tab opened and attempting to close by right clicking the button on the taskbar. I will edit the title of this bug report.
