Salut Bill, in an simple example I tried with qt and gtk and that ComboBox_click() is not fired here. gambas2 2.19.0 rev.2613 As you told, you striped of a lot of code. One idea, make a Source archive (Ctrl+Alt+A) from your project, unpack it in a different place, load it into the IDE, and try it. -- Amicalement Charlie [OperatingSystem] OperatingSystem=Linux KernelRelease=2.6.24-26-generic DistributionVendor=ubuntu DistributionRelease="Ubuntu 8.04.3 LTS" [System] CPUArchitecture=i686 TotalRam=506932 kB [Gambas] Gambas1=gbx-1.0.17 Gambas1Path=/usr/bin/gbx Gambas2=2.19.0 rev.2613 Gambas2Path=/usr/local/bin/gbx2 Gambas3=2.99.0 rev.2602 (can't compile actually) Gambas3Path=/usr/local/bin/gbx3 ------------------------------------------------------------------------------ Throughout its 18-year history, RSA Conference consistently attracts the world's best and brightest in the field, creating opportunities for Conference attendees to learn about information security's most important issues through interactions with peers, luminaries and emerging and established companies. http://p.sf.net/sfu/rsaconf-dev2dev _______________________________________________ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user
