WinXP, fully updated
Created an icon to a remote server on desktop.
Drag & drop file in explorer onto icon.
Dialog box, click "transfer settings" button, choose "configure.."
Brings up preferences dialog as expected, except that all the text of the lefthand tree is gone, replaced with a single space (judging from the size of the blue highlight).
Repeatable (happens every time).
Notably, this behavior was NOT present in icons created by and linking to winscp405. It brought up the preferences menu properly there. (Verified today, same server, etc.)
