Expert not updated

[chinaski]

Hello,

am i alone with the problem that my expert gets not updated for backtest when changing the code, compiling without errors ?

This happens sometimes.

Deleting .ex4, running backest throws an error "tester cannot load..."

So the correct EA is adressed.

After compiling without error, so new .ex4 availbed, code changes still not active. 

Restarting MT4, Editor, no help...
