Love Roundcube, I think it shows real potential (and is much nicer than Squirrelmail which I used before). However, I've got a rather annoying problem.
Basically, I run IE7 on Vista at work and like to check my email from work occasionally. However, I've noticed that when I go to my inbox (or any folder) list with IE7 the list of emails "creeps". It comes up quickly, but then it's almost like it refreshes each line of the folder contents list in turn, making each line taller by a few pixels. This means that every time I open a mailbox it takes at least 10-15 seconds before I can do anything with it. Once I've opened an email and closed it to return to my inbox, that same 10-15 seconds is repeated.
It's not critical, but it is annoying. It might be something in the way IE7 on Vista handles fonts but I'm not sure. I've tried it using Firefox on my Mac and everything seems OK... but I can't use my Mac at work!
Any thoughts or assistance, here?
