I'm using Sandboxie, too. How I think I got around the file attachment prob in IE was to be out of the sandbox. I tried that recently but had no luck. I may've tried with FF unsandboxed, too.
I don't like IE, so I'd really like to know how to tweak FF for the times I need those features. I can't even write in color unless I know the code, which I don't mind doing manually, prob'ly could in IE unsandboxed, too, but the file attachment problem I can't seem to get around anymore.
I have NoScript, which I have tried to figure out what setting is causing me not to see some features here. I tried undoing them, one at a time, but nothing worked. I've tried allowing everything (for this site only), but still have no luck.
I wanted to put a screenshot in a reply and I don't remember how to do that either, I'll look that up if I can.
Since I've been here, I've met some very kind, helpful, patient people.
If anyone has any ideas, please help. This is so embarrassing.
