[HELP] No preview window

[Selur]

I am confused.
Normally you should see two windows:

the left in my case is the editor, the right the preview.
When pasting the text and pressing F5, do both of these close?
If the editor does not close it should show something new in the log (at the bottom of the editor window),...

Once I paste the text and hit F5, the viewer opens and closes, slightly before the viewer script page.

All I see at the bottom of the script page is something about a Null PixMap, before the script window then quickly closes.

[Selur]

if you paste:

import vapoursynth as vs
core = vs.core
import site
clip = core.std.BlankClip()
clip = core.text.Text(clip, str(core))
clip = core.std.Trim(clip=clip, first=0, last=1)
clip.set_output()

Do you see:

do you see the same text in the preview window, or does it again simply close?
If you see a different text, what does it say? (I suspect at least the '_Number of Threads' should be different on your system)
If the Log in the Editor does show an error, what does it say?
