Have you tried the 'exact' same config fuse settings that are in your loader file
when programming it without the loader?

Solved finally!
That helps Bruce!
By careful comparision of every fuse programmed with and without bootloader I noticed some XINST=Extended Instruction Set Enable Bit which was dissabled in working version and enabled in non working version! In WinPicProgrammer this fuse is called "ENHCPU Extended CPU Enable". This fuse is related with some 18F specific data addressing techniques. To be sure that this fuse is my problem I reprogrammed several times exactly the same program (with other fuses the same) with XINST OFF and XINST ON and YES! With XINST ON the program is acting very strange and completely unfunctional. I try with programmer and with bootloader, symptoms are the same. So, dear friends, thanks everyone for help and write down in your notebook of 18FXXX' secrets following line:
cheers!Code:@ __CONFIG _CONFIG4L, _XINST_OFF_4L
