I have added a new field to UserVc
RecordAddBegin(UserVc,"UserVc_fuel");
RecordField(EmployeeCode, M4Code, 10,0);
KeyBegin(EmployeeCode);
KeySegment(EmployeeCode);

KeySegment(Code);
EndRecordAdd;


When I try to open customized edit window USDClass with this field added, the crash happens with error messages

c:\ctgwin\home\build\c85-2020-03-24-build\amain\vmint.cpp:981 assertion execp->stackSz==targetsize failed vmrinfo missing for now

and the next error message (both are visible at the same time)

WindowWcdp r1==NIL for window USDClass
The last error (WindowWcdp r1==NIL for window USDClass) is shown 3 times, then the program closes.


Is UserVc register customisable?
