There are some apps (most popular are Blazer, Phone) which cause crashes with DAs (that need UI) and popups/starmenus.
In 1.3b1, I have disabled macros in those apps because I can't fix the problem at this point. I think my next plan however is to enable the DAs and put a warning in the UI about Blazer and friends when a DA is selected (because the DAs without UI are useful to some).
In 1.3b1, I thought I had fixed the star/popup thing, but Sporty is reporting problems on the 755. I could get a crash once on the sim (the shadow window thing) but I couldn't reproduce it after that. Can people please let me know if they are getting star/popup crashes with 1.3b1 and Blazer or not, and what their device is ?
