qt4.4 pc specs requirements or qt3 support issue?

is there a certain pc requirements of qt4.4? like memory, processor etc.?

cause im trying to run a same program in the same OS but with different specs. pc1 has 512mb memory and a core duo while pc2 has 256 + 128mb of memory and P4, the output on pc1 is ok but in pc2 is a bug..

to be specific i convert my qt3 code to qt4 and its working. but after several testing we found this bug. I use QAccel to a line edit wherein when i press enter it will show a lookup and press ESC to close the lookup of cancel the entry. of course after converting QAccel it became Q3Accel but when i test it in pc2 after several Enter and Esc event the program will became IDLE or the lineedit will became readonly and will not accept any event.

now is this qt4.4 pc specs requirements or qt3 support issue?

"instead of using Q3Accel why not use QAction or QShortcut" yes this is already touched my mind but im avoiding recoding as much a possible but if its qt3 support issue i think i should reconsider it.
