0.33 - bug report

Post by Morning Star »

Hi Nikos,

This happened in x2 0.33 when I right-click-dragged a file from a pane over to a folder shown in the tree, waited for the little menu thingy to pop up, then clicked back on the pane with the left mouse button (without selecting anything from the popup menu)....

Here is the debug-mon output:

On second thoughts, this assert occurs whenever I use the right-click-drag menu at all... :(

this doesn't happen on my w2000
this could be an indication of leaking objects during drag-drop, which a few XP users have also observed, or it may just be x2 being too touchy

the only way to be sure would be to open a scrap frame, put in 2 files (each from a different folder), select+right drag them and see what happens (click on Ignore button to get rid of the assertion message box).

If there is no leak, you'll see in the debug output window that the object reference count has reached zero and no memory leaks will be reported by x2 when the program ends. Otherwise there's a real problem!

Ok. So I have two files from different directories in a scrap frame. If I right-click-drag to the other pane of the dual scrap frame, and select insert-here ot cancel, no problem. If I drag them into a folder back in the main pane or tree, the same assert message appears...

I hope that helps...

I just noticed, that assert comes up whenever I drag'n'drop, independant of which mouse button is used... so its not just right-click-drags that cause it...

i tried it on my XP and there were no problems, so the issue is fishy
wrt the little experiment with the 2 files in the scrap frame, please drag-drop to a target that is going to generate the assertion error. When it occurs click on Ignore button and see the output in the DBMON window. You'll see some lines like

MDOB(xxxx): Release, current lock count = xx

where all these xx will be some numbers
if the lock count goes down to zero, you're ok, otherwise there's a leak
also, when you quit x2 after this experiment, you can check the dbmon output right at the end for any reports of memory leaks that should reinforce the results of the experiment
