Problem with Wine /2

Sorry for not posting in a while, but the laptop worked just fine lately, so there really was not too much to be said.
The problem with Wine described in the previous post still presents itself intermittently. Oh well, anyway I pretty much got used to it, so if I have to launch any Windows application, I just do that and then I go out for a cup of coffee, so that when I come back the app would be loaded and running. :-)

Another problem with Wine occurred lately though. Although it's not really a problem with Wine, it's more of a problem with Firefox. In fact, when I visit a site which has a flash application (for example YouTube's movies) Firefox stops working and a Wine Desktop appears. As soon as I close the Wine desktop, everything goes back to working fine again.
Still, it's an odd problem, and I can't seem to solve it.

I've already uninstalled and reinstalled both firefox and the flash plugin, with no success.
Even reinstalling Wine did not work... who knows?
