Set and get dgData and dgText delay

[Craig Newman]

I have seen this here and there for years, and having nothing to do with dataGrids per se.

A handler will fail to run, but will step through in the debugger without issue. This usually resolves, and I never know why.

Stepping through in the debugger allows it to work or setting a breakpoint, but does not when in full run. Both in standalone and ide.
