So I'm now on SlickEdit 27.0.0 and a few days ago I noticed I had a My SlickEdit Config directory under Documents and didn't remember why and so I just deleted it to clean up a bit.
Well, 27.0.0 still has the same problem that running vsdiff doesn't use my current config. So did this drop through the cracks or is there no way to get it to work without the workarounds?
One odd thing I noticed was that the vsdiff.exe process (this is Windows 10 x64), has the SLICKEDITCONFIG environment variable still set to my default of C:\Users\bej\SlickEdit, but the vs.exe process started from vsdiff has SLICKEDITCONFIG set to C:\Users\BrianJongekryg\Documents\My SlickEdit Config\.
