alert message is not visible in windows 7

[rezaamya]

in the documentation there is a sample that will not show anything if click 'Item A', I found that it will show alert but it's not visible and if I press "Space key" on my keyboard, it will press 'ok'.

but if I change the Compatibility for the NW.exe, for example to Windows Vista, it will work:

the problem is I can't tell everyone to change the Compatibility mode! and also, some other features like sounds, will not work truly in compatibility mode...

@rezaamya In which version of nwjs did you run? I have a similar problem here, but it is in the newer version v0.23.6, I want to check before opening an issue.

[rezaamya]

@EdvaldoLima I am using nwjs-v0.23.6-win-x64. same situation is for nwjs-v0.23.6-win-ia32 too.

[EdvaldoLima]

@rezaamya ok, can you handle the alert, close, click "ok" normally?

[rezaamya]

@EdvaldoLima if you mean without using NWJS, yes I can, if you mean, inside the NWJS, I can't see the message but if I press Space on my keyboard, it will press "ok" and I can continue using NWJS, before pressing Space key, it's like freezing, but in fact the focus in on the alert box and I can't do anything before closing (by clicking on the "ok") the alert box.

@rezaamya many thanks for the answers, I can reproduce the same problem on Windows 10 x64, version 0.23.6-Win-x64 on the NWJs.

looks like this bug is due to my "transparency" code, introduced on nw23.6
and this bug should also affect win 8 and 10
on my win10 machine, you can see the alert, but you can't click it

there is a workaround, you can run "nw --disable-transparency"
meanwhile I'll try to find a solution for this

@rogerwang I've made a pull request nwjs/chromium.src#88
to fix this issue
please also patch nw24, really sorry for this bug

[rogerwang]

@jtg-gg no problem.

Fixed in git and will be available in the next nightly build.
