Hi
I think you mean the image in the Clip bin and not the preview. The option to change clip speed is not available from the preview screen........ only the Clip bin thumbnail and the Timeline clip.
Changing the speed of the clip bin thumbnail does not alter the speed of the same clip already on the timeline.However if the same clip is now re-added to the timeline the new speed is used for that clip.
Anyway...When you select either of these options do you actually get the Speed change dialogue window.If so, at what point does the clip disappear? (Obviously it shouldn't)
If you have had to re-create your project from scratch Save it before you continue with trying to change the speed of a clip.
If it then still crashes, completely empty all the cache files, either manually (if you know how to pull up your cache folder,) or from the Options page as Borate describes. But do this BEFORE you reopen the .vpj file to rebuild your project. This will ensure that ONLY the project files actually used are loaded to the cache.Normally a crash should be followed by a crash reporting screen when VP is restarted. so send a report. The problem may point to a faulty installation so you could try reinstalling.
VP 7.39 works fine here when a clip was tested with speed changes varying from 1% up to 500%.
