This is my personal opinion about Beta versions:
1) It's a
TEST version
2) They have bugs and may crash your system
3)
NEVER use it to replace your previously working version
4) Most beta releases come with a warning that highly recommend users not to uninstall their previous release versions and hightly recommend users to install it in a different directories.
Note: Most users ignore opinion #4
5) It's designed and released as a Beta version so users can tell the software folks what's wrong with it so that the software folks can fix the problems before the final release.

I have 2 previously working QCharts versions (they work great) and the current Beta 4.2 (causes to many system problems...but fun to play around with)...ALL installed in different directories.
Note: I test all beta stuff on days when I'm not trading or finish trading and I highly recommend those using Beta version software from any developer to truly understand what the purpose of Beta releases.
Thus, many users of QCharts Beta program should re-read information about such releases:

Therefore, too many traders treat their software like their trading....they get rid of what works for something untested or new.
