problems with block diagram selection

Hello all,
I experience some problems in LV 8.2 I have not seen before in other LV- Versions. When I use the mouse scroll- wheel to change the displayed portion of the BD and then select some code by drawing a rectangle, the selection frame appears at a different position. But the area I actually want to select appears selected. I use the Auto-tool. I can force this behaviour by doing the following:
  1. scroll the BD
  2. take care, not to touch any element on the BD (wires, terminals, SubVIs...)
  3. draw a selection frame
This works for scrolling up-down and for scrolling left-right by placing the mouse-cursor at the scroll bars. But it doesn't happen when I scroll by drawing the scroll bar.
I appended some pictures to show this.
Has any one experienced this too and is there some fix available?

I can't duplicate the problem.

Usually problems like this are related to the video driver. Sometimes updating, or jusr re-installing the video driver will take care of the issue. It could also be a mouse driver problem. I'd also try upgrading/re-installing the mouse driver.

Let us know if either of those takes care of the problem.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.

Hi Ed,
I replaced the video driver with an older version and installed the original Logitech Mouse driver (before I had the generic MS- driver), but it didn't help. I saw the same behaviour on a colleagues computer, but he has the same type of computer. It is no big thing, so I leave it as it is. Thanks for your help,
Dave

Hi daveTW,

I tried to follow your description and got the same problem. I can tell you that we know this problem and we are working on this to fix it. During this time I can only please you to click the right mouse button before you want to mark the code.

Regards

This doesn't appear to be fixed in 8.2.1. Is the CAR for this issue still being worked?
