Ever since I set up my new computer, I have been experiencing serious problems with keypresses in the programs I am compiling.  I have found that the programs themselves are running slower (I have had to lower my key delay by about half) and pressing a key for an extended period of time, say 5 seconds, causes the calculator to completly freeze...

Does anyone know what could be causing this.  I have tried compiling Block Dude, Trapped, the Ndless demo, Ncaster, and bwang's picture viewer and the problem persists in each case. 

Also, would someone be willing to compile Block Dude for the Nspire CAS for me? I had a compiling error in the version I uploaded to ticalc.org (I used the NON CAS header), and I need to upload a new version ASAP.  I have attached a .zip of a skeleton containing the block dude files.

Both, I have only experienced them on hardware, but in an e-mail conversation with someone using a fixed version for the CAS, they told me they had problems too.

apcalc, I'm not sure if this is related to your issue, but could you try to add the "volatile" keyword to the definition of isKeyPressed in common.h ?

#define isKeyPressed(key)       (!((*(volatile short*)(KEY_MAP + (key).row)) & (key).col))
The behavior may be  undefined with some versions of GCC without it.

Also, thanks _player1537 for compiling this for me

Hmm...I should update the skeleton accordingly.

This problem is not caused by my computer OS (thankfully)!

Before my computer was reset, I used to compile/store my programs in the Ndless folder, using the header files from Ndless.

When I started fresh on this computer, I started using bwang's skeleton, which did not contain "volatile" in the "isKeyPressed(" function.  The problem was caused because I was including a different header.

The behavior probably depends on the version of GCC.
