Something happened to my computer last night and I have been unable to fix it (haven't tried a system restore, yet, but I'm hoping to avoid that because it's been a month or so and I forget which desired changes I've made). It's not just in TurboCAD, but it is affecting things here, too.
Function Keys <F6> and <F7> do not work for selecting objects. In Windows itself, the Alt-<F4> hot key doesn't close the active window. The <Alt> key works fine (i.e., <Alt> F), so it's not a keyboard problem.
Other hot keys work just fine (Ctrl-N and Ctrl-T, for example).
I have explored various technical pages (changing things in service.msc didn't work; neither did rebooting or changing the USB port for my keyboard).
This is most likely not caused by TurboCAD (as I have the problem even when it's closed), but it affects TurboCAD, so I'm hoping that this is something someone else has encountered and fixed.
I have Windows 7 Pro.
Thanks in advance,
TC Pro Platinum 2017, 2016 & 2015 (all with LightWorks) & V21
