<p>I wrote an application in Java and when it runs on one customer's computer running OS X The Save and Export buttons are disabled. (Everything else works in the application.)</p>

<p>Both of these buttons open up a standard save file dialog.</p>

<p>Any ideas?</p>

The fact that these buttons open a file dialog probably has nothing to do with it being disabled. Buttons can end up being disabled for a number of reasons,
its
```
setEnabled
```
can be called with
```
false
```
,
when using an action, its
```
setEnabled
```
can be called with
```
false
```
, and
when using an action, it can have a property "enabled" that potentially disables it; see
Action
for more information, there's a list of properties there.
Could you post how you 'implemented the JButtons'?
