I would like to report, that I'm still using standard (non steam version) [Thank you so much Tom] and I have not had a single issue, I mean nothing, nada, zip.
When using steam version I was crashing all day long, and countless other issues.
When using standard version (non steam) I haven't had a problem, even the closing the program glitch has disapeared.
I have been using it a lot recently too, so really been pushing it.
Bottom line: I am so thrilled that I am going to purchase business version now (standard, non steam off course).
For those who look at steam forums for construct. Steam has deleted many topics related to any mention that steam causes instability with construct2 and other programs (one day they are there, next they are wiped out)
