• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

FS2004 Scrolling window problem

hi Don, sorry, it's me again...
1. load AIFP (latest development version)
2. load a traffic bgl
3. click Bulk Traffic
4. click T&PA
5. click Aircraft utilisation
(all fine till now)
6. scroll the window down a little and you get a incomplete window
see picture:

I was looking for a reason to stay indoors at my computer this fine, sunny summer weekend

Look for an update soon.

I was not able to duplicate your situation exactly, but something similar happened for me - the top line of the window was cleared whereas it was the bottom for you. What gets cleared is what was previously selected - so I'm hopeful the fix I applied will also work for you.

Please give Development Release 3.2.09(d) a try.

If it doesn't work for you, then, since you only had a single traffic file loaded, please send me that file together with step by step instructions for duplicating the issue.

3.2.09(d) did not solve the problem.
I attach the traffic file.
The steps are exact the same as described in my first post.

If I scroll further down, the window is emty and if I scroll up again all data has disappeared, even the data of the first display

Oops. I missed the scroll part in the first message. But, at least there is one less other bug to bother someone.

This will take a while Guenther. I had assumed when I developed this feature a number of years ago that the control type I used would look after vertical scrolling - as most such controls do. Turns out not to be the case. So I've got to rewind my mind about 5 years to recall the "whats and whys" of that development - and then do it again - the right way.

Surprising this deficiency in such a useful feature has gone unreported until now.

I suggest you enjoy your weekend and think about later.
If nobody has a problem (nothing crashes), it is only a "nice to have".

There are so many other features of AIFP to use and enjoy.

Upon further investigation, the Assignments control type does manage the scroll bars. I just neglected to enable the operation.

Development release 3.2.06(e) fixes. (really!)
