bug when using "High contrast mode"

[crazyfwed]

Hello,

When I enable the "high contrast mode" on Windows 10, there is a bug in Labwindows 2017.

I tried several ways to save my project, but none works. Usually it just silently fails.

But, here is a way to get an explicit message

- launch cvi

- create a new project

- drag and drop a C file to add it to the project

- click on "build"

- click on "yes" to save the project

- "some files failed to save", but click  "yes" anyway

- click "yes" again

- you now have a message "unable to open file .... (badly formed pathname)"

I have reproduced the bug on 2 different machines (both running win10-64 and cvi 2017)

I can only confirm it happens on my system too, following your directions.

It happens with CVI 2019 beta, too, with a difference: the message popup at end ("unable to open...") does not appear at all.
CVI IDE seems unable to open the SaveAs common dialog when "High contrast" theme is enabled.

Hi crazyfwed -

Unfortunately, I wasn't able to reproduce the issue that you described. I tried both with CVI 2017 and CVI 2019.

Could you provide more details about your setup?

1. What is the specific Windows 10 version you are using?
2. Did you change to high contrast theme before or after opening CVI? Does the issue reproduce with any variant of the Windows 10 high contrast theme (#1, #2, etc.)?
3. Where on disk did you try to save the project? Is that in a protected location?

Best regards,
- Johannes

I can respond too, the problem happened to me on both a real PC and on the virtual machine in which I've installed CVI 2019 beta.
1) On both system Windows 10 is the latest version, 1809 (build 17763.316), italian language

2) I've changed to high contrast theme. I've tried only the default one for me "High Contrast Black". I haven't tried other themes
3) The bug does not allow you to arrive a point you choose a location: the Save As dialog box does not open!

In detail:
Start CVI, create new empty project, add an existing C file with drag & drop.

Try to Build. This message box appears:

Click Yes. Normally here CVI opens the SaveAs common dialog, but instead appears this:

Click Yes. Another message box, this time CVI would like to save the project:

Click yes. No SaveAs dialog, but this:

That's all.
Repeating a couple of times the sequence, the last message does not appear at all.
In CVI 2019 beta the last message does not appear even at first attempt.
