As part of my customization to the TS3.5 Ful OI (LabVIEW version), I wanted to modify the splash screen that normally comes up (Full OI - Launcher.vi). I made a copy and renamed it, and I call IT instead in the Startup VIs section of my Build Specifications (under the "Source Files" category (I had previously extracted all the OI files from the LLB and placed them into a LabVIEW project so as to allow me to customize/rebuild as needed). The block diagram stayed identical, I just replaced the TestStand splash with a custom bitmap. I see varying results. Sometimes, the entire bitmap I placed on the front panel (which is about 1/2 the size of the TS Splash) appears. Sometimes, just the bottom 1/3 of the bitmap appears. I thought maybe it was related to the size of the front panel, so I've played around with the size. Currently, it's displaying properly, but this makes no sense. The new Launcher.vi and the Full OI - Top-Level VI.vi have the same parent directory, but they reside in different subfolders (if this helps). Are there any rules that I'm unaware of here?
