Description

It seems that on the latest Flash Player versions, MaxWarnings = 0 is equivalent to MaxWarnings = 1. This may be a bug: this is a fairly late change as this parameter worked as documented in spring 2020.

Adobe documentation

Sets the number of warnings to log before stopping.

The default value of the MaxWarnings property is 100. After 100 messages, the debugger version of Flash Player writes a message to the file stating that further error messages will be suppressed.

Set the MaxWarnings property to override the default message limit. For example, you can set it to 500 to capture 500 error messages.

Set the MaxWarnings property to 0 to remove the limit so that all error messages are recorded.

MaxWarnings = 0
