I don't think this can happen. Usually, timer events stack up while another method is executing.

from what I understand, autoyield pertains to Windows events, not internal VFP events, except when ActiveX controls are used, they play by their own rules.

>You may want to look into the AutoYield property (try HELP AUTOYIELD). It determines whether events are processed between lines of code or only during a wait state.
