NC Editor crashes on long files (27MB)

[Ivan Ionov]

Hello,

UCCNC works fine with long files, but when I try to press Edit button (to remove manually some lines from NC header), the software crashes.

After crash and restart the software lost 2 things -
1. machine coordinates are set to zero (annoying but not very critical, I can restore it moving to home switches)
2. work offsets are lost after crash - that's very bad, because even after homing I can't continue my work, this was a finishing toolpath after 3 hours roughing, so I had to realign somehow and loose accuracy.

Could you copy the Exception details please?
I guess it is an out of memory error as the file is probably too large to be loaded into the Richtextbox?!

Here it is -
