TOAD table editor crashes when trying to scroll while data is invalid

Can reproduce this both in Schema Browser and in the Describe window. Sometimes I get an access violation, sometimes TOAD just disappears.

CREATE TABLE toad_test AS ( SELECT ROWNUM AS rn FROM dual CONNECT BY ROWNUM <= 1000 );
ALTER TABLE toad_test ADD CONSTRAINT pk_toad_test PRIMARY KEY ( rn );

Open the table in Schema Browser or describe it (F4).
Duplicate a row (will violate primary key once trying to insert).
Use the mouse to move the vertical scrollbar.

For me the only thing that happens is that I get the expected Oracle error.

Are you using 32 or 64 bit Toad?

64 bit.

When I click on the arrows of the scrollbar, the error message is displayed and the scrollbar disappears. I can get it back by resizing the window.

When I drag the scrollbar, a lot of error messages seem to appear and within a second, TOAD is gone.

I managed to get an Access Violation this time, sent you the log.

Oh yeah, I see what’s happening now, thanks.
