Ren, thank you for the reply. I am using both the cRIO-9033 and cRIO-9035. I am aware of the KB. However, I'm looking for consistency programmatically for the GUI in both Windows and Linux RT environments. I was hoping for a Linux feature that is the equivalent of the *.ini file in Windows, but I'm guessing that doesn't exist.
For anyone who may be looking for a similar solution, the way I worked around this is via brute force. It's a bit tedious to program, but it worked great. I used a conditional compile against the 'OS' Conditional Disable Symbol. If 'Win', I didn't do anything and just let the *.ini file control the font sizes. If 'Linux', I created a utility VI that extracts references to all of the FP controls/indicators and decorations and sets the font sizes of each of their components (Caption, text, boolean text, number, etc.). I tested the error out for each of the class types via the 'To More Specific Class' function to determine which type of object it is. For example, if it's a String control/indicator, I set both 'Caption --> Font --> Size' and 'Text --> Font --> Size'.
Happy coding!
Eric
