Text colour changes after copy & paste

Hmm... not sure to understand. Captivate projects are always based on a Theme. A theme has Fonts, Color palette, Object Styles and Master slides (some minor extr components). Captivate has NO text styles, only object styles. Since Captions, Shapes and buttons can have text, the 'style' for the text is included in the object styles for those objects.When you paste such an object (you didn't tell which kind of object) to another project, it will normally take on the style of the Theme in that project. What has changed in 11.5 is the possibility to have multiple themes in one project. I wonder if this is the case in your workflow?  Which object did you copy/paste? Do both projects use exactly the same Theme? Did you not override the style for the object in the source project (you would see a +sign next to the style name)?

Here is a possible workaround which I described in a blog. 11.5 has a new feature 'copy/paste appearance'. If you select a text within a text container, you can copy the text style only, and then paste it to any other text not only within the same project but also in another project. You need to select the text in the target project before using Pasre Appearance.
