maybe this is related to this bug: FIXED: Clicking container crashes td

And for chrk120, just a tip: your bug can be solved quicker by Derivative if you file a complete bugreport.
-Is this Windows or Mac
-which build No ?
-Can you attach a *.dmp file (windows) or crashreport (mac). For Mac you can find the crash reports via ​Applications->Utilities->Console. The Crash reports will be under User Reports and named TouchDesigner099_date-xxx.crash.

If it is related to the bug that nettoyeur linked (i.e. you are crashing when you click twice on the button), then it should be fixed in build 2017.10800 or later. There’s also a work around I posted in that thread.

If it is a different reason, then crash reports would be very helpful.
