[R] Help with strange RGui behavior? Will not consistently run source.

[Eric Berger]

HI Stephen,
The reason I suggested the test was that I had a real flakey and
annoying GUI problem a couple of years ago.
It had to do with selection by mouse etc. The IT group could not
reproduce the problem (when they connected remotely) and I realized
that when I worked from home I also avoided the problem.
By fluke I found that when the problem arose I could "fix it"
(temporarily) by disconnecting/reconnecting my USB keyboard. My point
is that the problem was some weird interaction between hardware and
software. Eventually the problem more or less disappeared with some
updated version of Windows 10. (I was somewhat relieved to find that a
lot of people were complaining of the same symptoms, but no one could
provide a fix that worked for me.)

Good luck!

My ability to adjust window dimensions took a serious slide (cursor on edge or corner, click and tug). Usually only works now if I pause for awhile after the click before moving the cursor, while it used to work immediately every time. Similarly my ability to select text with a scroll became more difficult, but shift-clicking works fine. I just assumed my mouse was succumbing to age (still think that likeliest), or possibly related to the last Windows update a few days back (coincidental timing). So I doubt this is pertinent but thought I should mention it just in case.
