I use Opera for Panda Crazy and Overwatch. That way Chrome doesn't get overloaded. Don't know if that'll help.
I - In my Opinion - would just use one browser for anything mturk related. I tink I remember your computer specs. you should be able to run everything from/through chrome, take it easy on the number of "tabs" you have open at any one time. I run Panda Crazy in its own window. Right click on the icon for chrome and select "new window" I think that is the windows way - I'm a Ubuntu user so I just click the icon and get a new window with chrome running. But yes reinstall.
So I just get the group id and paste it into panda crazy and that'll work?
right click the part in hit scraper that shows the dollar amount, copy link address, go to panda crazy, click the "add job" button, paste the whole link that you copied there, select the "collect only once box if it a single hit - or not if is a batch, then click the "Add Panda for group ID hit" button, should be good to go then.
