Enabling keyboard in 'function shaper' VST crashes

Lots of crashes when using enable keyboard for typing in formulas in robin schmidt’s ‘function shaper’ vst effect

What I do …I Load functionsaper …enable keyboard …type in a formula …dissable keyboard when function is written …that when renoise crashes …no renoise warning just a windows warning.
Doesn’t happen all the time , but happens a lot

Log file

Can’t seem to make this happen here and the log unfortunately also is not really helpful here. Could you give us a few more hints on when this happens?

no I na’t sorry taktik .
Like I said , renoise crashes wihout a warning , windows does …so the log probably doesn’t give alot of info …
Happens verry random
