[SHOWTOGROUPS=4,20]Unexpected popup window when debugging in RAD Studio 10.4: Workaround
David Millington 10 Jun 2020
An unusual bug in 10.4 where an unexpected dialog can appear when debugging has a workaround: temporarily disable the Welcome screen.
There is a bug in RAD Studio 10.4 where, when debugging, you may get a dialog you did not expect appear at apparently random times. It may not be fully visible, such as displaying the title bar and only part of the window. After closing the dialog, debugging may continue or you may experience instability leading the IDE to close.
The issue is somewhat unexpected: it's caused by the Welcome page. Specifically, it's caused by the new feature where Для просмотра ссылки Войдиили Зарегистрируйся. The Welcome page checks for any new patches being available in a background thread, and a threading issue causes a modal dialog to be shown incorrectly and from a non-main thread.
We have a fix for the issue and will issue a hotfix soon.
Workaround
In the meantime, there is a workaround: to disable the Welcome screen. Do this via the registry (so take appropriate precautions.) In the Registry Editor:
или Зарегистрируйся.
Other notes
As a side note, this post highlights two things that our users sometimes do but we suggest doing differently.
The first is that, if you disable IDE packages, some people delete the entries. We recommend not doing this but adding an underscore (_) at the start of the description. This is the official way to disable a package located in this registry location. We usually don't recommend doing this at all (some packages can depend on others), but if you do, it allows you to restore the package easily if you need to.
Second, some information on social media suggests toggling GetIt between online and offline mode by editing the registry. This is not recommended. The correct way to do this is to Для просмотра ссылки Войдиили Зарегистрируйся and run GetItCmd.exe -c=useonline to turn it to look online for data, or GetItCmd.exe -c=useoffline to turn it back to offline / ISO disk installation.

In the meantime, there is a workaround: to disable the Welcome screen. Do this via the registry (so take appropriate precautions.) In the Registry Editor:
- Open the path "HKEY_CURRENT_USER\Software\Embarcadero\BDS\21.0\Known IDE Packages"
- Locate the string entry "$(BDS)\Bin\startpageide270.bpl"
- Do not delete it. Instead, edit it. Its value is the description, "Start Page IDE Package". Add an underscore at the beginning of the description so it reads "_Start Page IDE Package"
- Open the IDE
