Is there a known bug in gSender that causes crashing?
I have now had three instances of gSender going unresponsive after a milling run has finished. It only happens after a milling run. I get the window that says the job has completed but I can not close the window. The only way to get out of this is to close gSender and re-open it.
I am running the latest regular version of gSender (1.4.14 ?) on a gControl computer.
Running anything else on the gControl? Have you checked for recent Windows updates?
Did you upgrade the ram?
I don’t think I use mine gSender/AltMill as much as you but I typically leave gSender running on my gControl - have never had a crash or freeze.
I have nothing else running on the gControl.
I have isolated the gControl from the outside world so no windoze updates.
The ram was not updated.
I typically leave gSender running as well.
What I haven’t done but will do now that I think about is to reboot the gControl just in case something got screwed up somewhere. I didn’t think about that since windoze itself never crashed - just gSender crashed … but it’s been a while so I might as well do that (belts and suspenders kinda thing)
If you have updated gSender at all, it may require that Windows be updated as well - since it likely calls upon resources that Windows provides and some of those may have had updates.
And yes, unfortunately, Windows does require the frequent restart - recommended weekly in most cases but monthly at minimum. This clears caches and restart services that may get bogged down or orphaned.

Rebooting the gControl computer did not fix the problem 
I will log a help request with Sienci Labs.
Oh, I am running 1.4.12 and not 1.4.14 …

Sienci labs returned a suggestion (kudos, within one business day !!) of deleting .sender_rc on the hard drive, (windoze path is C:/users/{your username}/.sender_rc) and then re-open gSender.
I won’t have a chance to try this for a while but thought I better update things here.

Deleting .sender_rc did unfortunately not help. I am hoping that Sienci has another suggestion.
I would like to update/close this thread:
Sienci Labs has graciously provided me with a replacement controller. The new controller did fix an issue with what appeared to be an intermittent USB port but unfortunately it did not fix the original issue.
I am now working under the assumption that the issue is based on a software problem. Since the freezing only happened at the end of a longish job (just shy of 3 hours) and since it didn’t actually impact the job itself, I am going to just live with it under the assumption that sooner or later the issue will be fixed.
Sienci did request I try gSender 1.5.0 Edge 8 but I was not able to clearly determine if the crashing still existed. There was some evidence that it might be fixed but since 1.5.0 is still in beta with other issues, I have decided to stick with 1.4.12 for now and just close out and re-start gSender if/when it freezes.
I would like to give kudos to Sienci Labs for their quick response and for providing the replacement controller! Way-to-go guys!
