Evaluate: Unhandled C++ exception!

[kingcrimsonster]

When I enable some filters, AVS viewer window closes with error:

Evaluate: Unhandled C++ exception!
(C:\Windows\Temp\tempPreviewAvisynthFile05_32_20_701.avs, line 27)
..... avsViewer error output - END ---

Preview script itself seems fine:

Does it work if you reopen avsViewer?

Some filter combinations cause problems when they are killed and restarted ot fast, which is why 'Synth auto refresh' is disabled by default. (like mentioned in the tool-tip)

Yes, after reopen avsViewer, preview working.

Then it's an expexted effect and the reason why 'Synth auto refresh' is disabled by default.

if the 'Synth auto refresh' is disabled, then it will become very difficult to work.

Still there is nothing I can do about it.
-> Either don't use Hybrid or live with the fact that you sometimes have to restart the Avisynth Preview.
