Hello,
I have reports from my customers about your new version 2.50 (beta). When they use my UltimateListView product with it, they get a Fatal signal 11 (SIGSEGV), i.e. a violent crash. Some examples work, some others don't. Since my product doesn't use any special memory trick or system hack, and works fine with B4A v2.30, it seems there's a bug in your new version. Unfortunately, I don't have the new version (and for obvious reasons with beta versions, I prefer to not install it), so I cannot help a lot. I can provide you with logs sent by users. Here's one of them (unfiltered).
If you have no clue about this, I will install a virtual box on my computer to test the new version.
