DirBox in VB3 Shows Long File Paths Instead of Short Names, Breaks App - Can't select folders with spaces

[chentiangemalc]

Describe the bug
The VB3 DirBox normally in Windows XP shows Short File Paths, but under OTVDM shows long file paths. Seems to be using a 32-bit control as the FindFirstFileW doesn't seem to originate from otvdm.
