hi there

LV 8.0: there seems to be a bug in the Text File IO functions. Incomming errors set the refnum to NULL.

Topic is discussed here: http://forums.ni.com/ni/board/message?board.id=170&message.id=204042&jump=true

No thread for this, just some weird behaviour I noticed after upgrading to 8.2

When resizing text using the <ctrl> and +, there's a small display bug.  Added 'junk' goes away with scrolling.

Kennon confirms that if you are using a custom run-time menu in an exe, "ctrl-E" is not available so you can not debug an executable.

He also offers some advice on how to deal with the complication.

NathanT confirms that there is a (minor) bug in the linking of type defs inside datalog file refnum controls (fixed in LV 8.2)

This is probably more of a "limitation" than a "bug", but in this thread:

Jarrod S confirms that there is no way of using the "latch" mechanical actions on a boolean control inside an XControl, without additional code outside the XControl.  There is no way internal to the XControl of forcing the Facade VI to run again in order to reset the output value, so even though the button on the Facade VI instance resets after it's read, the "Data Changed?" value isn't updated, and the reset value doesn't get sent out to the parent VI.

Roy F confirms that LV will not (without help) utilize more than four proccessors.

He confirms that using the "threadconfig.vi" utility will correct that situation.

A CAR has been filed to investigate.
