Can you please be a little more specific about a few things, so we can try to diagnose the issue?
What OS are we talking about - Mac or PC? Which version of the OS? What are your system specs? What are the project details - source footage, frame rate etc.
Please can you be as detailed as possible too - this is sounding very alarming to me because we use transcribe all the time these days (it is never correct but it gives placement for editing) and when you say it is not possible to edit text unless you 'select a blank area of the timeline' - eek. A series of screenshots, a film clip - anything at alkl to try & nail this one down.
Until then, I am not updating at all & appreciate the warning too
All projects (around 5 I've tested even a blank project from scratch), all types of audio, .wav, in camera audio etc. footage from all sources, Sony cameras (25/50/100p), Red, and screen records. Its just become really bad.
Itll take me about 5-6 attempts to even get the transcript going, preesing different options till one works, not good at all.
