I've set rememberlastfolder to false to work around the problem...but has anyone else noticed this problem or have any other workarounds? I'm using version 2.0x or something. Is that addressed in a later release? By hanging i mean the typical behavior when an application stops responding on windows... Thanks, Jaisen http://www.fotoflix.com

Try to turn off it using following code: Code: `<param name="SignatureFilter" value="All">` Our next release will have turn off signature filter by default.

Is there a way to only enable certain files to be selected for upload (aside from filtering what's displayed)? I wouldn't want to do it strictly on the serverside since the files would have to be uploaded before they're checked for type. Maybe some javascript to check the extensions of files in the upload list and remove or notify the user for non-image files.

Code: `<param name="FileMask" value=".jpg;.jpeg;.jpe;.gif;.png;.tiff;.tif;.psd">` Edited by user Monday, October 27, 2008 11:59:40 PM(UTC) \| Reason: Not specified

On other side when we check file singature, image width or height, we need to read it from file. Opening file is rather expensive operation, that's why it causes "hanging".
