Hi afre,
I tried the suggestions without success.
As for others, dt 2.4.4 installs and reinstalls without problems. I also think it’s not hardware-related (my pc uses a Radeon graphics card).
On my laptop, a click on the parameters (gear wheel) generates a backtrace:
In this file, I read: Access Violation at location 0000000066882B18 in module libthai-0.dll.
This last point seems corrected in RC2 …
