RT Target may crash when closing the block diagram of a running VI with the MathScript Probe
If you are running a VI on a Real-Time target with a MathScript Probe attached to a MathScript node, closing the block diagram may cause the target to crash.
Workaround: Close the MathScript Probe before closing the block diagram.
Removing inner function in .m file breaks VI
When a referenced .m file contains two functions, one of which calls the other, removing the bottom function (and changing the top function to not depend on it) breaks the caller VI.
Workaround: This is just an extraneous error appearing in the error list window. If all the other errors in the caller VI are fixed, the VI becomes good.
Attaching a probe to large MathScript Node while running on RT can cause connection loss
If a large MathScript Node is running on a RT target and you try to attach a probe, you occasionally lose connection to the target. If you then reconnect, the probe will work normally.
Running 'clc' clears the output of some commands executed after calling it
If 'clc' is used, it should clear the output window then run the script that follows it. The output window should populate with the output of the rest of the script. Instead, 'clc' ' clearis the output of some of the later commands in the same script.
Cannot drag multiple variables between local and global categories
If multiple variables are selected from the tree in the MathScript Window and dragged between local and global partiton/variable, only the one will move.
LabVIEW MathScript hangs when calling a large model
When loading a script with a large model (generated from another software tool), LabVIEW MathScript will hang. This behavior is due to the fact that LabVIEW runs out of memory when processing such a large model.
