minimize and restore error

[Ian.W]

Definitely! I meant it as clue that might help NI figure out the bug, but on re-reading I can see how my choice of words was poor.

We all know the value of informative error reporting; hopefully others will report their details too.

Edit: speaking of informative reporting, I have CVI 7.1.1, XP SP2 (up to date) on a Dell D600 laptop

Hello checkers

Thanks for giving us this sequence of steps. Based on these steps, we've beeen able to reproduce the problem in-house, and we are currently investigating a fix which will be included in the next version of CVI. The reason that this has been hard to reproduce is because in addition to these steps, a couple more factors seem to be necessary:

1. CVI has to start up already maximized.
2. You have to minimize CVI from the task bar button, and not from the minimize button in the titlebar of the window.

If we follow these requirements, with the steps you mentioned, then we are able to reproduce the problem consistently (for the first time, I might add).

One thing I would ask at this point, would be that if you (or anyone else) can reproduce the problem in some other circumstances, or even if you can reproduce it by removing one of these requirements, to please post the detailed steps here, so that we can make sure that we address it.

Thanks again,

Luis

Hi Luis,
I might add that sometimes I also see the behavior when I use the Win+D key combo to show the desktop. I might run some program from the desktop, then click CVI in the task bar to go back to programming, and sometimes it doesn't redraw properly unless I minimize or restore down.

Thanks, Orlan.

We tested The Win+D case and were able to reproduce the problem in CVI 7.1. It happens the first time that you hide CVI after it starts up maximized. It looks as if this is the same underlying problem as the "minimizing from the taskbar" case, and we verified that this case is covered by the same fix.

Thanks again!
Luis

I am glad the this has finally been duplicated by NI...
"Thanks for giving us this sequence of steps. Based on these steps, we've beeen able to reproduce the problem in-house, and we are currently investigating a fix which will be included in the next version of CVI."

However, I hope that I can get this fixed without having to shell out another $1495 for the next version of CVI. Can't you target this as a bug fix and make a distribution, like 7.1.2 maybe?

There is defenately more scenarious where this occurs. I had a couple of occurances since I upgraded from 6.0 to 7.1 about 6-8 weeks ago and my screens looked diffirent. I will pay closer attantion and try to repeat my steps and see if I could nail it down. I repeated the steps as described above and that works for my system as well.

I'm Running Windows 2000 SP4 on a Dell Dimension and CVI 7.1 with 256MB Memory.

Here's my contribution:

We are seeing this on multiple PC's. There seems to be multiple causes for this.
I initially thought the problem was my original PC (which died recently after 2 months of use).

I will try the minimize on the task bar and report any findings.
