Delphi 1 causes system to crash

I am running Delphi 1 on a Win95 machine Pentium II 166 with 32 megs ram.
Frequently I receive an OE exception (blue screen) when running the project
through Delphi. It usually happens when you use a control (ie click on a
button, use a menu, etc). It does not occur at the same place and does not
always happen. Sometimes in is accompanied with a GPF in Delphi's de{*word*81}
A reboot is always needed. Sometimes it is quite persistant, ie happening a
few times in a row and sometimes it won't happen at all.
I know it is hard without the extact description of the exception , but any
ideas would be appreciated.
