These are all very insanely good hypotheses, and they are the same ones i came up with, unfortunately, I haven't been able to test them yet, due to the fact i've been in bed all day with my upper back giving me screams of agony.
Yes, this is the right track, and as soon as I can sit up for more than 5 mintues, i'll start trying some of these approaches
It is worth noting that this LMCE launch manager was ported from the original LMCE Launch Manager, which was a Qt4 app. Jondecker rewrote it, and it is possible some bits are still missing. I tried to fill in the remaining functionality as best i could, but maybe we're still missing some needed initialization.
Again, thank you so much for looking into this.
