Alert Message Keep on poping up

I use the Browser Alert Action in the Eventsheet and build my project in HTML5.

Sometimes when I run it the Popup Message will appere and when I click the OK button the Popup Comes back up again. Same message too.

This also happen when I'm writing my plugin in javascript and have multiple Alert message one after the other.

It's just shows the 1st Alert message over and over again.

My colleagues don't seem to have this issue on the computer with the build.

Any Ideas as to what is going on and how to fix it? Thank you

It's hard to tell for sure but maybe you need to add a trigger once condition.
