I was about to say that 1.9a RDP with using TSGW isn't working ... but then I entered my credentials in the "Use seperate Login Credentials" ... and it works.
The credentials I use are the same credentials I use for the RDP connection ... so technically it shouldn't be required for me to also enter the same credentials in the "Use Separate login Credentials".
Other than that, 1.9a seems to be working great for my RDP connections. Our system has just implemented a TSGW and I was lamenting not being able to connect using my all time favorite RDP connection program (Terminals) ... but 1.9 now includes the
TSGW options. Good job.
