There seems to be a problem with 226 PC build. There are loads of entries in MQL4.com.

My MT4 keeps crashing. I have attached the dump below.

1. It does it on my PC at home, and my PC at work.

2. Both my PC at home and PC at work are Windows 7. I have tried it on two XP boxes and it crashes as well.

3. It only crashes with my EA running. Over the weekend, because there were no ticks, it didn't crash even though my EA was loaded.

4. The EA uses no external DLL calls.

5. It crashes with an MT4 error box - so the crash is actually being handled, rather than giving me a "Do you want to send this to Microsoft?"

7. Here is the crash dump which is identical to many other people's:
