Extended Trends Problem

Extended Trends Problem

Currently I'm having a problem with the extended trend feature.
I have setup a trend screen and use the extended trend picture type to get the relevant data into the trend. I use a picture switch function from the menu bar to pass all of the relevant information into this trend and to open the screen.
This works fine when I run the program on my laptop but when I download the project onto the PDA the trend screen will not open.
I have checked the help files but I don't see any info that would indicate that this feature is not supported by the CE runtime.
I'm currently using the Demo licence for the CE runtime and was wondering if this could be the reason for the screen not opening.
Additionally the variables I'm trying to display are obtained via a modbus connection.
Any information would be great.
