Hi Dave, my testing result is :
-used my "BROWSERTEST" VirtualBox vm (OS2 WARP4.52) which is same one implemented for you Simple Browser revisited, means QT5 Pentium4 necessary packages installed
-VIRTUALADDRESSLIMIT=3072
-RAM given to the machine also 3072 MB
-execute mark_high.cmd in /usr/lib
-tried both dooble versions downloaded in their zip archive from the given url; first version and the gcc11 one, executed from their folder just unzipped under C:\, they give same results
-browser starts in its blank page, then I can opens some pagesite but some of them self-close or trap after about a minute (ie. Youtube, Linkedin)
-almost behaving like the Simple Browser revisited which opens any pages only in Incognito mode, also there Linkedin and Youtube pages seem to work initially, resist a minute +/- , and then trap. The common part is both browsers cause a system trap as want to exit (close) 90% of the times
-both browsers can stay open sametime on the pages they can handle.
So, by my poor knowledge side I can tell they share same unstable behaviour happening more on less on same site pages, like it was caused by same -one or more- dll involved.
Just a question: does mark_high.cmd need to be executed every starting session ? If so, is it good to put its shadow in the Startup folder or adding such command in autoexec.bat?
Thank you
