I've posted a new version of RemoteViewing, 1.0.0. Here's the link: https://software.seekye.com/remoteviewing
It adds support for 16-bit color mode. I found one of my virtual machines used this mode, and RemoteViewing did not previously support it.
It also fixes mouse coordinate scaling on the Windows Forms control. Thanks to mike10 for reporting this bug!
Enjoy!
God bless.
