File selection isn't working
//echo -a $sfile($mircdir\*.zip,title,ok)
EDIT: Well actually confirmed on 7.38 is not working the Files of type: when you select the Zip Files (.zip) only on zip files this issue has been occurred.
On 7.39 this issue has been fixed!
21.Extended file dialogs to include more file types in the file types listbox.
Thanks for your bug report. Unfortunately I have not been able to reproduce an issue with the example you provided. When I test it out in mIRC v7.38 (or the public beta v7.39), it displays the file selection dialog and lists only the zip files in the $mircdir folder. I select a zip file and click the OK button and it is echoed in the status window.
