// - FOS_SUPPORTSTREAMABLEITEMS doesn't seem to be supported on windows vista, or at least not with the flags we use
|
|
// - even with FOS_NOVALIDATE the dialogs will reject invalid filenames (at least on Vista, anyway)
|
|
// - lack of FOS_NOREADONLYRETURN doesn't seem to matter on Windows 7

// - when a dialog is active, tab navigation in other windows stops working
|
