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.
