The VSD file open dialog on UNIX allows you to type in the names of files you would like to find. You can enter directory, file, and * wild card characters. These act as an additional filter on the visible files in the main pane.
If you navigate to another directory, the File names pane is cleared, but the filter remains in effect. This may cause existing files to be filtered out of the view.
This is a TCL issue, related to the TCL file dialog introduced in v5.1 to provide new file opening features.
Close the dialog and reopen. VSD will remember the directory you were viewing and start off in that location.
