We have a strange problem since moving to 15.x and higher with the 64 bit application via RDP.
When having collapsed all groups in the group panel of the Data Grid, scrolling over the groups with the mouse wheel causes the random expansion of groups. This is not related to the RDP as 14.x was working fine via RDP.
We are puzzled what the reason could be. Is this an issue somebody else has experienced ?
Welcome to the Toad for Oracle forum, BTW.
I can reproduce an experience similar to what you describe, and I'm not even accessing Toad via RDP... looks to be happening from Toad versions starting at 16.1 (at least).
Sending a short vid to the Quest Toad Dev team. Thanks for calling this out.
I can reproduce the expansion. Looks like it started in 15.0.
Thanks for reporting it. It will be fixed in Monday's beta.
It seems to only happen when scrolling by mouse wheel. up/down arrow keys do not cause the problem. It was caused by a change we made to work around the grid's built-in throttling of fast mouse wheel scrolling. I'll just revert to the old method of scrolling if the grid is grouped.
VERY much appreciated. We use this functionality all the time and it really causes head aches. 
I am using version 16.3.231.2085 and I get a similar problem. Anywhere in a data window, changing or initiating grouping always picks one group to open, usually the last one. Scrolling via mouse wheel will open a random group as the scroll continues. This sounds very similar to what the OP was seeing. Has the change been included in this version? I am using an MS Master 2S mouse from Logi, in case the driver there could be part of the problem.
Hi Stanzoid,
This was fixed in version 16.3. I just retested it to make sure. I am not sure why you are experiencing the problem in that version, unless you found it in a grid that didn't get fixed. I just tested version the Editor (F5 and F9) grids, as well as schema browser data tab. I have a MX Master also.
I assume you are talking about grouping by dragging a column header here like in my screen shot.
If you are doing something different, can you post a screen shot?
