Comment 78 for bug 772207

I also have some problems, as others I have version 173 listed but not active and the recommended is activated but not in use.
VGA card is 6200 Turbocache.If Firefox is running and I also open Thunderbird then T'birds opening page is fine but if I then go to the write page then I get a white screen but for the 3 screen icons in the top left hand corner. This does not happen if Firefox is not running, it has only started since upgrade to 11.04, also I had it set so that the screen, how to explain, went wobbly as it changed from min to max, now I cant set that up, silly thing but it's not right.The white screen thing also happens when say on Facebook I try to save an image the page goes to what should be a directory listing but instead shows the white screen as before.
I have got the Unity app running as it was automatically installed for me when I upgraded to 11.04
Another thing I've noticed is that if I run Thunderbird first and then Firefox then I get the white screen as explained but by running the mouse cursor about in Google (my home page) I can find the search bar as the cursor changes to a flashing upright bar, so running blind if I click on that, type something and press enter the prog seems to be running but nothing appears, I know it's there though cos I can track where the text is with the mouse cursor.
I'm a bit of a newbie so be gentle with me. Firefox 4.0.1 Thunderbird 3.1.10
Sorry to be a bit long winded but more info must help,........I think.
