Hi Dave
Yes, sites with lots of images and javascript eg ebay cause dooble qt5 to quit fairly quickly - 5 to 10 mins use if lucky. Less "busy" sites usually last a little longer, maybe 20 mins, and some sites do not work at all. Sadly the qt6 version usually quits after a few minutes regardless of how "busy" a site is.
Possibly upping VAL value would help - but it would screw up other apps that are more important.
Regards
Pete
