Too many R/C commands in a loop?

[ManicMechanic]

The attached program uses 8 commands in a loop, with the first 4 allowing the left joystick in R/C to shift a holonomic drive up/down left/right, the last 4 allowing channel 5 to spin the bot. When I insert the first 4 commands in the loop, the bot shifts properly. The last 4 commands in the same loop (without the first 4) spins it properly. But all 8 commands in the loop causes the bot to go berserk. Does 8 commands force it to sample too frequently? And how do I work around the problem? When I insert 2 loops sequentially, it never makes it to the second, because the first condition is always true.

A secondary problem: how do I copy and paste text in EasyC? I had to do a screen shot to post the program.
