That's it! Thanks for pointing me to the crash report. I had no idea that existed. The crash report indicated the failure was with rtsultramonhookx32.dll. That sounded familiar so I checked and it is related to multi-monitor software I had installed called UltraMon (which has always been a very useful tool for me, but I don't use its features as much as I used to). To check the relationship, I uninstalled it and now I can launch Mail without any issue. Looks like something about UltraMon became incompatible with SeaMonkey Mail. I can certainly live without UltraMon for a while - more easily than living without Mail. I'll report a bug to them and see if they can fix things.
Thanks a ton!! _______________________________________________ support-seamonkey mailing list [email protected] https://lists.mozilla.org/listinfo/support-seamonkey
