If you create an instance of a symbol containing a timer, then create another instance of it, only the latter (duplicate) instance is active.

This is due to a deliberate restriction on symbols in VBA projects. The number of symbol projects created is not the same as the number of instances because:

• Each one uses system resources for loading and operation (through a memory restriction in VBA).
• With identical, active symbol projects, it would not be possible to change all instances of a symbol by changing one symbol project.

So there is one VBA project for all instances of same symbol. The VBA project is dynamically connected to its instances when an event is received at an interface (MouseClick, MouseEnter etc.).

In the case of the timer, no events come from the interface (unless one passes the mouse over another timer instance) so the latest current context is used.

Advice

The VBA code associated with a symbol must be run from a mimic by these events:

• MouseEnter.
• MouseLeave.
• MouseClick.
