A possibly related issue: I use autohotkeys (AHK, a replacement for the venerable AllChars) to expand short strings into longer ones, like say an email address:
]jg => Joseph.Something@gmail.com
AHK is extremely useful in that it can do a lot more than this simple example, so I use it a lot. For example, to enter date and time I use ]dt which expands to 4/2/2020 2:47 PM.
However, when remoting in with RU, it does not transmit the upper case or shift, so that the email example becomes joseph.something2gmail.com
While an email address is not case-sensitive, the @ becomes 2 (the lower case for that key), which makes it unusable. The date & time in RU expands to 4/2/2020 2;49 PM which is also incorrect.
If I remote from the same laptop to the same host machine via other remote software like UVNC, [censored] , or RDP, this does not happen. The string expansions happen correctly. In fact, I can simultaneously remote into the host machine via RU, UVNC, and [censored] , to try the expansions into the same program like Notepad, and the problem only happens with RU. I have tried the RU settings for Scan code and Unicode, and they make no difference. Any ideas?
Actually, problem not quite solved yet. With the above suggestions I can see the mapped drives, but attempting to drill down a drive's folders inevitably pops up the "unable to open this directory" message. It does drill down one or two levels before the message pops up, but once the message is displayed it goes back up to the root. Odd.
