Browser crashes after upload is interrupted

I tried using Maxthon (my PC uses Windows 8, 64-bit, last version, plus I have Java/Flash both updated) to upload files to Google-Drive.

It worked, but then I rebooted my VDSL modem. if you have used Google Drive, you'll know that if the browser remains open, it will state "you are offline", and once the connection is restored, which in my case takes 1-2 minutes, the uploads will continue, because GOOGLE DRIVE supports resume.

Currently (and this is going on for days) I am uploading to other browsers, too. When I rebooted the modem, Maxthon crashed, interrupting the upload and closing.

All other browsers waited to continue. Which tells me this is a confirmed bug from your browser. The other browsers tested were Firefox, IE, Opera, SeaMonkey and Comodo IceDragon. Now I am using Chrome instead of Maxthon because this interruption forced me to upload from the start a few GB. 

My broadband speed is 35 Mbps (download) and 3 Mbps (upload). I have multiple Google Drive accounts, so letting the PC on for a while will finish all my desired uploads.

Once this bug has been addressed I'll continue to use Maxthon for this.
