I've seen this mentioned in a few threads, with no clear answer as to why it's happening (not clear to someone who is code illiterate). Logging in during a raid with certain raid frames active (Grid, for me) causes a complete freeze on the first screen at login. I've switched to CTRA frames to get by, but the aesthetics and level of customization offered by Grid makes me want to switch back ASAP.
Is the freeze something that needs to be reported to and fixed by Blizzard? Or would I be better off posting in Grid's Bugcatcher?
