just a head up, the new version issue > freezing CAT
This is what i think
Click Market with Statistic Calc > close windows (probably fetching data in the background)
Click Market again, it freeze (Due to, there is an api call still runnig in the background)
At this point pretty much CAT not useable till the api call complete from getting Market data
But we wait for the a few minutes and the call completed, it will function normal again
