I was using v.18.104.22.1680 and I could open 100+ sites, leave it so for 16h+ come back and everything was so how I left it. Since some websites are broken with it and couldn't watch videos online on specific sites I needed to upgrade to v.22.214.171.1240.
After some time, it can be a minute or an hour and everything goes black, websites, new tabs, mx://last-visit/, EVERYTHING. Refreshing doesnt work, I need to close and reopen tabs but sometimes I need to close Maxthon to be able to surf the net. It's really annoying if you have open 200 tabs and there's another 200 in mx://last-visit/, so closing Maxthon and reopening the last 200 is really grueling.
I'm using Win7 64bit and RX 460 with 16.11.5 driver.
