[erlang-bugs] GUI debugger Module view crashes in dual monitor setup

[Peti Gömöri]

Hi Mat,

debugger supports both the old gs and the new wx gui framework
By default it tries to start the wx version if wx is available otherwise
falls back to gs.
>From the error report I think you use the gs version.
As far as I know gs is not supported really by the OTP team any more.

Can you try to reproduce it with wx gui: debugger:start(global, default,
wx).

You might need to install wxWidgets in order for this to work.
