Microsoft has released a pre Beta 2 version of IE7, and there are a few issues with MiceChat:
Problem: WYSIWYG Editor Doesn't Show Correct Text
Analysis: IE7 doesn't update the editor as often as earlier browsers.
Solution: Use the Standard Editor (Preference can be changed in User CP)
Problem: Some MiceGames Arcade Games do not work
Analysis: Some users have not upgraded to Flash 8
Solution: Update to Flash 8
Problem: Occasionaly when browsing, I get a "Suspisious Website" box in the Phishing Filter
Analysis: This is due to the fact that MiceChat may collect your Date of Birth on some pages. Note that we do not use this information for more than age-checking purposes. We have allready contacted Microsoft to fix the problem.
Solution: None at this time.
Problem: Some RSS Feeds do not properly show in IE7
Analysis: IE7 only works with RSS2 and ATOM based feeds.
Solution: Make sure you are using http://www.micechat.com/forums/external.php?type=rss2
These are the only known IE7 problems at this time.
