Hi QLers, I’m between work and home and did find some time to make some short videos about the freeze case. Here they are:
QL/E (v3.11, SMSQ/E v3.22, QPAC2 v4.02) freezes! http://youtu.be/wcngRwkvc5w QL/E (v3.11, SMSQ/E v3.22, SMSQmulator v2.12) freezes! http://youtu.be/HZ9jj162UN4 QL/E (v3.11, SMSQ/E v3.22, QPAC2 v4.02) workaround prevents freeze! http://youtu.be/D07vYHsvA80 QL/E (v3.11, SMSQ/E v3.22, QPAC2 v4.02) no freeze when QDT is disabled! http://youtu.be/b-rc6PZASyc I’m posting this message with my iPhone and will reply to all your replies when I will be using my home PC, but this can be later on this week. QL forever!
