eJ 4.90 crashes at the start of speaking a song announce on Vista x64 SP1 when using 32-bit high quality voices such as AT&T Natural Voices.
This is more of a Vista problem than an eJ problem although the fix is to modify the eJ shortcut to run program as Administrator.
The only reason I know this to be related to Vista is that I've written some speech programs in VB.net that couldn't access the 32-bit speech
libraries on x64 without first being recompiled exclusively as 32-bit (x86) and run as Administrator.
I'm not entirely sure how you can code around this, but if you have some tricks up your sleeve, please share...
