It appears Cerulean Studios may have fixed the recently discovered Yahoo! Messenger connection problem that caused Trillian to crash on Yahoo! authentication. The patch is still in beta although it appears to work fine for most but others are having problems with it. The patch can be downloaded from the members area of CS web site but it will only work for Trillian Pro 2.0 users at this point.
Here is the message that reads in the members area of CS web site:
A beta version of a patch to fix the recent Yahoo! connectivity issue is now available for Trillian Pro 2.0 users. Please test this patch and let us know if you experience difficulty; this patch may not work for all users. We will issue final patches for 2.0, 1.0 and .74 as soon as were confident everything is functioning 100%.
