Found bugs in HP-15C LE

[Namir]

I was unsuccessful in finding the bug list for the HP-15C LE on this site. I think I found (new?) bugs while testing the timings for the Permutation and zcombination functions. I use the I register to loop a number of times. Normally (with other functions) the LE displays blinking "running" while the time test program is executing. However, in the case the Permutation and zcombination functions, the screen goes blank. When the timing test program finishes, the LE displkays the current value in the X register.

The effect of the blank displays slows down the test program. I think whatever is prventing the LCD from displaying the message blinking "running" is slowing down the test program.

Are the above bugs new or someone else has already found them?

PS: In the HHC2011 timing test presentation that I gave, I did not test the speed of the Permutation and zcombination functions for the 15 LE calculator.
