Flex UI Inconsistencies

I am having some issue with consistency across different machines with my flex application.

There are three things that I have noticed with my application. On my development machine (Windows XP) I can not reproduce these issues.

I have noticed them on a Windows Vista machine as well as a Windows 7 machine.

The three things that I have found are:

1. Label's will be truncated with '...'
2. Tabs in a tab navigator will be truncated with a '...'
3. Some Images will be rendered with an inconsistent width and height

My labels are defined pretty simply

<mx:Label x="261" y="15" text="Date Prepared" fontWeight="bold" width="113"/>

Tabs are custom components but defined in a pretty standard format:

    <mx:TabNavigator borderStyle="solid" 
        x="10" y="10" width="665" height="450" id="tabs" creationPolicy="all">
    <local:FormPanel id="formPanel" name="formPanel" 
           label="Incident Details  " 
           width="665" height开发者_如何学Go="450"/>
    </mx:TabNavigator>

You may notice extra white space following the label in the custom FormPanel, I have found that this might help solve a subset of the truncation issues (not 100% sure).

As for my images, again, I am not doing anything to amazing:

<mx:Image id="vehicle_image" 
    source="@Embed(source='../../../../../images/icons/basic/vehicles.swf')"
    height="45" width="45" toolTip="Vehicles" 
    toolTipShow="handleToolTipShow(event)"
    click="showBar(event, vehicle_bar)" enabled="true" x="47" y="0"/>

The image is contained in a canvas and I will have about 10 of these images all sized 45x45. On certain machines I will see 3 of the 10 images rendered smaller what would appear about 30x30 relative to the other 45x45 sized images.

The problem I am having is that I can not reproduce these issues on my development machine, and do not have any clue on how to fix these issues. I would expect that the things I am seeing are bugs in the FlexSDK, but even if they are bugs I do need a temporary work around.

Any ideas?

For some reason it won't let me add a comment, but.. This sounds a lot like some of the changes (CSS fixes) put in from Flex 2 to 3 (maybe 3 to 4 as well?) (Button components can do this too if the width is a fixed size.)

Are you absolutely sure that your development machine is running the same version of the app as the others? If you're using Flex/Flash Builder's "run" functionality to run on the dev machine, but building and deploying with Flex Ant tasks or some kind of separate build for the others, it's possible to have this happen by using different SDKs even though the code hasn't been changed at all.
