Brian -
This reminds me to a very (very) similar issue described by a customer creating installation kits and sending to customers in Korea.
This was reported to R&D (# 1SFBAB8M) and was fixed in LabWindows/CVI 5.5.
Sir -
Help me to understand your issue a little better: is this the case that you literally don't see the "Done" button (you see the gray parent background behind the button), or does the button exist, but seems to be displayed incorrectly. If the first case is happening, posting a screenshot would be very helpful!
Also, some additional information would be quite helpful:
-Is one machine the development machine, or are both running distributions?
-If both are distributions, are you using the same distribution of the CVI Run-Time Engine (RTE) on both machines?
-Are these RTEs installed from the distribution created to distribute the program, or is one (or both) downloaded from ni.com?
-Are there similar service packs for Windows installed on your machines?
-And finally! (thanks for your patience) are both these mentioned instances running the same program, or two different programmings both happening to call DirSelectPopup()?
Thanks!
