Mark - sorry, it's me again - but for the past week or so, sometimes when I've painted text either in order to copy and save it, or to delete it, both in the quick and main reply boxes, the options box comes up but my screen freezes and I end up losing the whole blinking lot! For example, tonight I lost a response to James on the Sociology thread which had taken me over an hour to think up and type.
Obviously the answer is to save text in lengthy posts more frequently, so's I don't lose too much, but it's still going to be a problem.
Again this only happens on MW, but if it's of any help to you, the relevant window on the taskbar (and I'm now Windows 7) shows yellow/orange and I'm unable to delete it, because when I right click to get the "close window" option, the window starts blinking, and I end up having to click on another window or go to the Start Menu and click on IE in order to get back into MW. The only way I can get rid of these yellow windows is by shutting down or restarting the computer. My W7 manual isn't any help here.
I have no idea what problem you are having but it certainly has nothing to do with MW. You say it only happens on MW but that's probably because you only are in this particular scenario on this website. I would suggest doing the usual maintenance to your computer (defrag/ccleaner etc). What browser are you using?
Whilst your computer is causing problems, you may want to consider typing big replies into a word processor like Microsoft Word.
If I had to guess at what problem you had, I'd probably say Spyware/Adware, so consider downloading 'Spybot Search & Destroy' and doing a full scan of your computer.
