<p>If you put up an <code>NSAlert</code> while your app is in the background your dock icon starts bouncing and keeps on bouncing until you switch back. </p>

<p>I find this annoying. </p>

<p>Does anyone know how disable that for a single app? </p>

Not that I'd recommend it, but there is a Haxie that may help:
Dock Detox
.
They allow you to intercept the bouncing and do other stuff, I think.
A quick google showed up:
```
```
- (void)cancelUserAttentionRequest:(int)request
```
```
But I really don't know if this will work for your purposes.
