Problems with 12F675

[fratello]

I write this code. It's something wrong :
- if I press but1 and rel1 goes low because of 'check' (over-load detected), but2 don't work not at all (must disconect power), and rel1 goes high only after two press of but1 ;
- if I press but2 and rel2 goes high, if I press but1 rel2 goes low ;
- if I press but2 and rel2 goes low because of 'check' (over-load detected), but1 don't work not at all (must disconnect power), and rel 2 goes high only after two press of but2.
Can help me ? Thanks in advance.
btw: The 'check' subroutine works fine !
