Why did i loose my chat room smiley's when yahoo messenger updated?
If you are having problems with Messenger 8.0 Beta, fill out this feedback form http://add.yahoo.com/fast/help/us/messen... Make sure you select 鈥楳essenger 8.0 Beta Problems鈥?from the dropdown field in #3. Also, if the problem you are experiencing is making Yahoo! Messenger unusable, I suggest going back to version 7.5. To do so, go to http://messenger.yahoo.com and click on the 鈥楪et version 7.5鈥?link located directly under the 鈥楪et it Now鈥?button to get the current version, version 7.
