Namely, move the drive dropdown to just the left of the path text box and don't include the former in the latter. This improves the UX on Windows. In the UNIX case, since its concept of drives is (ab)used to provide shortcuts to useful paths, its dropdown is kept at the original location.

[03:57] <reduz> yessopie, so i don't havemak to rely on unicows
|
|
[03:58] <yessopie> reduz- yeah, all of the functions fail, and then you can call GetLastError () which will return 120
|
|
[03:58] <drumstick> CategoryApl, hehe, what? :)
|
|
[03:59] <CategoryApl> didn't Verona lead to some trouble
|
|
[03:59] <yessopie> 120 = ERROR_CALL_NOT_IMPLEMENTED
|
|
[03:59] <yessopie> (you can use that constant if you include winerr.h)
|

[03:59] <CategoryApl> well answer with winning a compo
