I tried using Ltk a while back (running Phil's Able editor), and immediately ran into the kind of problem you report. I found that bringing up a msgbox as the first thing to do, and dismissing it by pressing Enter (not by clicking) was one way to avoid the hang. Unfortunately that's all I can add. I'm pretty sure there are a few more people that would be very happy to see this bug get fixed. I hit it and just stopped trying to do GUI programming, so if it get's fixed, I'll be very happy, and willing to test things on my 'eerie' computer.
